Normalize filter overexposes video

Description

Summary of the bug:
In the recent versions the normalize video filter broke. Previously it stretched the contrast, now it blows up the color space towards white. Comparison with v4.2.2 can be found here: ​https://github.com/fourMs/MGT-python/issues/145#issuecomment-713516121
How to reproduce:

% ffmpeg -i input normalize output
ffmpeg version 4.3.1
built on Windows 10

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

Hey richardpl,

Is this something you already noticed earlier? Can we expect the fix already in the next git builds?

Thanks a lot!
